Facing this section of the line was the village of Bailleul which was abandoned by the Germans, and was taken over by Pereira's Second Division, who had relieved the Highland Territorials upon April 13. Shortly afterwards the Sixty-third Naval Division took over from the Thirty-fourth. These two {54} divisions belonged to the Thirteenth Corps (M'Cracken), which from now onward occupied a space in the line between the Seventeenth to the south and the Canadians to the north. The strong villages of Oppy and of Gavrelle lay now in front of the British in this quarter, but the German line was destined to remain unbroken for a considerable period. An attack was made upon Gavrelle by the 190th Brigade, the landsman unit of the Naval Division, but this was only partially successful. Farther to the north the Second Division had no better fortune against Oppy, which was attempted more than once. The further advance against these places will be found recorded further on, where it will fit into its place among the other incidents of the renewed general attack upon April 23. [Sidenote: April 13] The Canadians in the Vimy Ridge area were occupied during three days of dreadful weather in consolidating their new positions, and in pushing the Germans out of that northern portion which they still held. The Fourth Canadian Division had suffered much from machine-gun fire from Hill 145 in the Souchez district, but this was taken upon April 10. There was still a good deal of work to be done, however, at that end of the line, and upon April 12 a joint attack of Canadians and British cleared the ground in this quarter. Attacking at dawn in a snowstorm, the resolute Canadian infantry drove their way over the northern limits of Vimy Ridge, capturing among other positions an outlier of the Vimy Ridge, the venomous little hill called The Pimple, which had been a thorn in their side. At the same time the Twenty-fourth British Division moved forward nearly opposite to Lens, the river Souchez separating them from the Canadians. The immediate obstacle which {55} faced the British troops was a scattered wood, the Bois-en-Haches, which was most gallantly attacked by the 73rd Brigade. The front line in this fine advance was formed by the 9th Sussex on the left and the 2nd Leinsters upon the right, supported by the 13th Middlesex and 7th Northamptons. Both the Sussex and the Irish battalions, especially the latter, had heavy losses, but they never faltered until their objective was won. Upon April 13 there was a general forward movement along the whole Canadian line, in the course of which they occupied Willerval in the south and both Vimy and Givenchy-en-Gohelle in the north. On the same date the 15th and 95th Brigades of the British Fifth Division took over from the Fourth Canadian Division from the Souchez River to south of Givenchy-en-Gohelle. These two brigades actually took over on the move forward, and did not stop until they had reached a line
